Abstract: A security label which is capable of deactivation is known for theft security systems in which a strip made of a soft magnetic material having high permeability and low coercive force is combined with a strip of higher coercive force to form a laminate. In this case deactivation is carried out by magnetising the strip having higher coercive force. A strip according to the invention having a higher coercive force and made from a ductile iron/chromium/cobalt-based alloy by rapid solidification at a cooling rate of more than 10<3> K/s, the mean particle size of the alloy being less than 30  mu m and its structure being virtually free of gamma- and/or sigma-phase precipitates, results in a security label which is largely insensitive to mechanical stress, especially when combined with a highly ductile amorphous soft magnetic strip. <IMAGE>

Abstract: Waveform data read out of a memory (12) is converted by a D/A converter (13) into an analog waveform, which is amplified by an amplifier (15), from which a waveform signal is generated. To cancel the generation of a distortion in the amplifier, a composite waveform composed of a distortion canceling signal waveform and a fundamental frequency signal waveform to be generated is written into the memory. To determine a distortion canceling signal, the fundamental frequency component in the signal waveform which is output from the amplifier when multi-sine waveform data is read out of the memory, is attenuated by a notch filter (17), and the signal waveform is converted by an A/D converter (18) to a digital multi-sine waveform, which is provided to a computation and control part (10) and subjected to a Fourier transform analysis to compute the amplitude and phase of each harmonic component. Further, the output of the amplifier when fundamental frequency sine waveform data is read out of the memory, is fed via the notch filter and the A/D converter to the computation and control part, wherein it is subjected to a Fourier transform analysis to compute the amplitude and phase of each distortion component. At the same time, the output of the amplifier is converted into digital waveform data without being applied to the notch filter and the data is subjected to a Fourier transform analysis in the computation and control part. By this, the amplitude and phase of the fundamental frequency component are computed. Based on the results of these Fourier transform analyses, the amplitude and phase of each frequency component of the distortion canceling signal are determined, which are used to compute composite waveform data composed of the distortion canceling signal and the fundamental frequency signal.

Abstract: A screw pump having a pair of screw rotors (8) meshed with each other and rotatably supported in a housing (6) having an intake port provided at one end and a piston (31) movably provided at the other axial end of the housing, which piston (31) defines a discharge port (5) in cooperation with the housing. The movement of the piston in a direction substantially perpendicular to the axes of the screw rotors enables the distance between a discharge starting position (PE,PE') of the discharge port and the intake port to be varied, so that the internal compression ratio can be varied. This arrangement ensures that the size of the housing will not be increased and any disadvantage due to the difference in thermal expansion along the length of the housing can be overcome.

Abstract: A double-pass two-dimensional spectrometer utilizes a telescope which contains only reflective optical components and is therefore free of chromatic aberrations. The telescope is so used in combination with dispersing optics (17,18) as to allow double-pass use of the combination. The telescope has a state of correction such that, for example, an image which is diffraction-limited at 800nm is produced over a flat field, corresponding to a wide-angle object coverage. This state of correction is accomplished with only two mirrors (10,11), one of which is a conic (e.g., hyperbolic) surface of revolution, while the other is a reflecting generalized polynomial aspheric corrector; and both mirrors are rotationally symmetric surfaces of revolution, each about its own axis of revolution. The double-pass nature of the system allows for a compact optical system consisting of only two reflecting surfaces, plus the dispersing optics, and there are no internal obscurations, thus avoiding negative effects of diffraction off of internal structures. The invention is shown for its applicability to each of several types of spectrometer-design configurations.

Abstract: A flat display panel (53) including a sandwich of thin film layers (52) with indices of refraction that increase the luminance and contrast of the display is disclosed. The sandwich of thin film layers (52), progressing backward from the front major surface of the sandwich, includes a front electrode layer (104), a front dielectric layer (58), a phosphor layer (60), a back dielectric layer (62), and a back electrode layer (64). The index of refraction of the front dielectric layer (58) is greater than or equal to the index of refraction of the phosphor layer (60), such that nearly all light rays projecting forward from the phosphor layer (60) pass into the front dielectric layer (58). The front electrode layer (104) can comprise relatively wide transparent strips, separated by small distances, or the front electrode layer (104) can comprise narrow strips (106) that are opaque and highly conductive. In the latter case, the front dielectric layer (58) extends between the narrow strips (106) and includes doped portions (110) that are conductive. The front major surface of the sandwich of thin film layers is covered by a protective faceplate (54). The faceplate (54) comprises a plurality of optical fibers extending from the back major surface of the faceplate to the front major surface of the faceplate. The fiber-optic faceplate (54) directs light rays projecting from the sandwich (52) to a viewer. The flat panel display (53) so directs light induced in the phosphor layer (60) that the image projecting from the faceplate (54) is very similar in luminance and contrast to the image induced in the phosphor layer (60).

Abstract: An image recognition system includes a method and apparatus in which images are characterised and compared on the basis of internal structure, which is independent of image size and image orientation. A library of reference images is first generated and stored, then each input image, or test image, is compared to the images stored in the library until a match is found. The image is represented in memory as nodes, lines, and curves. A plurality of descriptors, called reference keys and reference series, are generated for both the reference images and the test image. The reference library is screened for likely matches by comparing the descriptors for the test image of the descriptors in the reference images in the library. Inclusionary and exclusionary test are performed. After screening, each of the candidate reference images is searched by comparing the pathway through the reference image and the pathway through the test image, and by the degree of correlation between the reference and test images. In addition, the link ratio, a measure of the portion of the test image actually matched to the reference image is computed. Searching criteria, like the screening criteria are based on internal image structure, so that the recognition process is independent of image size and image orientation.
